Lake Nottely (also called Nottely Reservoir) is one of many reservoirs of the Tennessee Valley Authority. It is located entirely in Union County, Georgia in the United States and within the Chattahoochee-Oconee National Forests. Formed in 1942 by the damming of the Nottely River, Nottely Reservoir extends 20 miles (30 km) upstream to the town of Blairsville.
Construction of Nottely Dam began in 1941 and was completed in 1942. The dam is 184 feet (56 m) high and stretches 2,300 feet (701 m) across the Nottely River. Lake Nottely is approximately 20 miles (32 km) long and 102 feet (31 m) wide as well as an average depth of 10.6 metres (35 ft), a max depth of 98 feet (30 m) at the dam, and has a flood-storage capacity of about 61,588 acre-feet (75,968,000 m3). Its primary purpose was for flood control in the Tennessee River watershed, but in the 1950s a single 15 megawatt generator was installed for power generation. [1]
Approximately 70% of the shoreline is under the jurisdiction of the United States Forest Service and undeveloped. [2] In recent years, many new homes and properties have contributed to Lake Nottely's growing importance for recreation. Its proximity to Atlanta (2 hours) is resulting in increased use of this reservoir.
Blairsville is a city and the county seat of Union County, on the northern border of Georgia, United States. It was founded near the Nottely River, which was dammed in 1942 as part of the Tennessee Valley Authority project, forming Lake Nottely. As of the 2020 census, the city had a population of 616.
Watts Bar Dam is a hydroelectric dam on the Tennessee River in Meigs and Rhea counties in Tennessee, United States. The dam is one of nine dams on the main Tennessee River channel operated by the Tennessee Valley Authority, which built the dam in the early 1940s to provide flood control and electricity and to help create a continuous navigable channel along the entire length of the river. The dam is the technical boundary between the 39,090-acre (15,820 ha) Watts Bar Lake— which it impounds— and Chickamauga Lake, which stretches from the dam's tailwaters southward to Chattanooga.
Fort Loudoun Dam is a hydroelectric dam on the Tennessee River in Loudon County, Tennessee, in the southeastern United States. The dam is operated by the Tennessee Valley Authority (TVA), which built the dam in the early 1940s as part of a unified plan to provide electricity and flood control in the Tennessee Valley and create a continuous 652-mile (1,049 km) navigable river channel from Knoxville, Tennessee to Paducah, Kentucky. It is the uppermost of nine TVA dams on the Tennessee River.
Guntersville Dam is a hydroelectric dam on the Tennessee River in Marshall County, in the U.S. state of Alabama. It is one of nine dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s as part of a New Deal era initiative to create a continuous navigation channel on the entire length of the river and bring flood control and economic development to the region. The dam impounds the Guntersville Lake of 67,900 acres (27,500 ha), and its tailwaters feed into Wheeler Lake.
Nickajack Dam is a hydroelectric dam in Marion County in the U.S. state of Tennessee. It is one of nine dams on the Tennessee River owned and operated by the Tennessee Valley Authority, which built the dam in the mid-1960s to replace the outdated Hales Bar Dam 6 miles (9.7 km) upstream. The dam impounds the 10,370-acre (4,200 ha) Nickajack Lake and feeds into Guntersville Lake. Nickajack Dam is named for a Cherokee village once located just upstream from the dam. The village was the namesake for Nickajack Cave, which was partially flooded by the reservoir.
The Chickamauga Dam is a hydroelectric dam on the Tennessee River in Chattanooga, Tennessee, United States. The dam is owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s as part of a New Deal era initiative to improve navigation and bring flood control and economic development to the Tennessee Valley. The dam impounds the 36,240-acre (14,670 ha) Chickamauga Lake and feeds into Nickajack Lake. The dam and associated infrastructure were listed on the National Register of Historic Places in 2017.

Great Falls Dam is a hydroelectric dam on the Caney Fork, straddling the county line between White County and Warren County in the U.S. state of Tennessee. It is the only dam outside the Tennessee River watershed owned and operated by the Tennessee Valley Authority. The dam impounds the 1,830-acre (740 ha) Great Falls Lake, and its tailwaters feed into Center Hill Lake. The completion of Great Falls Dam in late 1916 was an engineering triumph, marking the first successful attempt to impound the volatile and flood-prone Caney Fork. The dam is also notable for its design, utilizing a mostly underground conduit to carry water from the reservoir via a tributary to the Power House 0.75 miles (1.21 km) downstream from the dam.
Apalachia Dam is a hydroelectric dam on the Hiwassee River in Cherokee County, in the U.S. state of North Carolina. The dam is the lowermost of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s to provide emergency power for aluminum production during World War II. While the dam is in North Carolina, an 8.3-mile (13.4 km) underground conduit carries water from the dam's reservoir to the powerhouse located 12 miles (19 km) downstream across the state line in Polk County, Tennessee. The dam and associated infrastructure were listed on the National Register of Historic Places in 2017. Apalachia Dam is classified by the U.S. Army Corps of Engineers as a high-hazard dam, meaning a dam failure may pose a deadly threat to nearby residents. The dam's condition is not made available to the public due to security concerns.
Watauga Dam is a hydroelectric and flood control dam on the Watauga River in Carter County, in the U.S. state of Tennessee. It is owned and operated by the Tennessee Valley Authority, which built the dam in the 1940s as part of efforts to control flooding in the Tennessee River watershed. At 318 feet (97 m), Watauga is the second-highest dam in the TVA river and reservoir system, and at the time of its completion was one of the highest earth-and-rock dams in the United States. The dam impounds the TVA Watauga Reservoir of 6,430 acres (2,600 ha), and its tailwaters feed into Wilbur Lake.
Cherokee Dam is a hydroelectric dam located on the Holston River in Grainger County and Jefferson County, Tennessee, in the southeastern United States. The dam is operated and maintained by the Tennessee Valley Authority, which built the dam in the early 1940s to help meet urgent demands for energy at the outbreak of World War II. Cherokee Dam is 175 feet (53 m) high and impounds the 28,780-acre (11,650 ha) Cherokee Lake. It has a generating capacity of 136 megawatts. The dam was named for the Cherokee, a Native American tribe that controlled much of East Tennessee when the first European settlers arrived in the mid-18th century.
Blue Ridge Dam is a hydroelectric dam on the Toccoa River in Fannin County, in the U.S. state of Georgia. It is the uppermost of four dams on the Toccoa/Ocoee River owned and operated by the Tennessee Valley Authority. The dam impounds the 3,300-acre (1,300 ha) Blue Ridge Lake on the southwestern fringe of the Blue Ridge Mountains.
Hiwassee Dam is a hydroelectric dam on the Hiwassee River in Cherokee County, in the U.S. state of North Carolina. It is one of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s to bring flood control and electricity to the region. The dam impounds the Hiwassee Lake of 6,000 acres (2,400 ha), and its tailwaters are part of Apalachia Reservoir. At 307 feet (94 m), Hiwassee Dam is the highest overspill dam east of the Mississippi River and is second only to Grand Coulee dam in the nation. At the time it was completed, it was the highest overspill dam in the world.
Nottely Dam is a hydroelectric and flood storage dam on the Nottely River in Union County, in the U.S. state of Georgia. The dam is owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s as a flood control structure and to help regulate flow at nearby Hiwassee Dam. The dam impounds the Lake Nottely of 4,180 acres (16.9 km2). While the dam was built primarily for flood storage, a generator was installed at Nottely in the 1950s, giving it a small hydroelectric output.
Chatuge Dam is a flood control and hydroelectric dam on the Hiwassee River in Clay County, in the U.S. state of North Carolina. The dam is the uppermost of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s for flood storage and to provide flow regulation at Hiwassee Dam further downstream. The dam impounds the 7,000-acre (2,800 ha) Chatuge Lake, which straddles the North Carolina-Georgia state line. While originally built solely for flood storage, a generator installed at Chatuge in the 1950s gives the dam a small hydroelectric output. At the time it was built, Chatuge Dam was the highest earthen dam in the world until the Aswan Dam was built in Egypt in 1964. The dam and associated infrastructure was listed on the National Register of Historic Places in 2017.
South Holston Dam is a hydroelectric and flood control dam on the South Fork Holston River in Sullivan County, in the U.S. state of Tennessee. It is the uppermost of three dams on the South Fork Holston owned and operated by the Tennessee Valley Authority, which built the dam in the 1940s as part of efforts to control flooding in the Tennessee River watershed. On October 21, 1950 the valve gate closed and water began backing up to create South Holston Reservoir. Work began on the dam in December 1941, but in November 1942, the War Production Board requested that the operation be suspended because of a shortage of critical materials. Work did not resume until July 1, 1947. The dam now impounds the South Holston Lake of 7,550 acres (3,060 ha), which extends northeastward across the Tennessee-Virginia state line.
Blue Ridge Lake is a reservoir in Fannin County, in the northern portion of the U.S. state of Georgia. The reservoir encompasses 3,300-acre (1,300 ha) of water, and a "full summer pool" of approximately 1,686 feet (514 m) above mean sea level. It is managed by the Tennessee Valley Authority and is primarily fed by the Toccoa River.
Lake Chatuge is a man-made reservoir in Towns County, Georgia, and Clay County, North Carolina. It was formed by the Tennessee Valley Authority's construction of Chatuge Dam in 1942. The lake is relatively shallow with depths of 30 feet (9.1 m) and reaches 144 feet (44 m) by the dam. In an average year the water level varies 10 feet (3.0 m) from winter to summer to provide seasonal flood storage. Lake Chatuge is the highest major lake in the state of Georgia. It takes up 7,000 acres and is 13 miles (21 km) long.
Norris Lake, also known as Norris Reservoir, is a reservoir that is located in Tennessee. The lake was created by the Norris Dam at the Cove Creek Site on the Clinch River in 1936 by the Tennessee Valley Authority (TVA) for flood control, water storage, and hydroelectric power. Norris Dam and its reservoir were the first major project taken on by the TVA. The lake, the dam, and the town of Norris, Tennessee are named for George W. Norris, who was a U.S. Senator from Nebraska and who wrote the legislation that created the TVA.
Hiwassee Lake is a man-made reservoir in Cherokee County, North Carolina. It lies along the Hiwassee River created by the Hiwassee Dam which finished construction in 1940.
